One in four of the 2,000 people quizzed use a single password for the majority of accounts and one in 20 (four per cent) sticking with the same login details for all their accounts.

Experian says people are putting themselves further at risk by no longer using many of their accounts - meaning passwords are not changed regularly.

Six in 10 adults (66 per cent) admit to having defunct profiles that hold valuable personal and financial information, including social network profiles (26 per cent), email addresses (18 per cent) and shopping accounts (21 per cent).
